Default Re: Breaking in a new motor

I agree... 16:1 will run your engine lean and let it get too hot, which is the enemy of break ins... For the actual break in procedure, you'll get all kinds of answers as well as some heated arguements in some cases. I'll just say don't run it for more than about 20 to 30 minutes the first tankfull and let it cool all the way down between runs, it's the heat cycling and overheat prevention that'll let your engine live a nice long life, so basically, Do Not let it overheat and you'll probably be fine, but don't let it sit there and idle out a full tank of gas either, the engine does need to be able to see the rpms it's going to run at later on and a light load which can be progressively increased to full load.
